J Dominance of Short Cracks in Bending and Tension

[摘要] There are many structural situations involving shallow cracks, in which it is not possible to make direct measurements of the relevant fracture toughness using existing British (BSI) and American (ASTM) deep notch fracture mechanics tests. The objective of the present work to establish the size requirements for a one parameter characterisation the crack tip fields for short cracks in edge cracked bars subject to tension and bending.
